Power Play: Status-sensitive men may strategically modulate their desire for intergroup dominance Nicholas M. Michalak Robin. S. Edelstein Personality, Relationships, and Hormones Lab Abstract Does feeling powerful (or not) affect men’s desire for intergroup dominance? In 5 experiments, men (and women in Experiments 2 and 5) recalled having power over others (high power) or someone else having power over them (low power). Then they reported their social dominance orientation (SDO), among other measures. We also measured men’s testosterone (T) reactivity (Experiment 4). We conducted an internal meta-analysis as well as a pre-registered replication on MTurk (Experiment 5) and found that the power manipulation had, at best, a trivially small effect on SDO. However, in experiment 4, we found a significant manipulation x T change interaction, such that greater T reactivity was positively associated with SDO in the low power condition and negatively associated with SDO in the high power condition. Despite the likely weak main effect of feeling powerful on SDO, testosterone reactivity may reflect sensitivity to power information, such that power-sensitive men modulate their SDO depending on their position in their status hierarchy.
